4 points:
1) I have been myself the victim of better books for a long time, because I had
written my book myself and it was very small. For example I remember I have been
caught by Diep in the blitz world championship (Paris, 1997). You have to live
with this, it happens. If you don't want it to happen, you have to find somebody
to write a strong book for you, and you can maybe also write automatic
algorithms to adapt an automatically generated book to the style of your
program.
2) Jeroen has not written a killerbook. A killerbook is a book in which you
insert games won by your program so it can replay them against KNOWN opponents.
Your program as well as the other programs in this tournament are not known
opponents.
3) Jeroen inserts novelties he has studied himself in his books. This is a hard
job to find novelties, and I don't see why it should not be rewarded also.
4) Gambit Tiger is going to be available soon. You can try to let your program
play against it with books disabled for both, and inform us about the results.
